Some variants of quantum theory theorize dogmatic “unimodal” states-of-being, and are based on hodge-podge classical-quantum language. They are based on ontic syntax, but pragmatic semantics. This error was termed semantic inconsistency [1]. Measurement seems to be central problem of these theories, and widely discussed in their interpretation. Copenhagen theory deviates from this prescription, which is modeled on experience. A complete quantum experiment is “bimodal”. An experimenter creates the system-under-study in initial mode of experiment, and annihilates it in the final. The experimental intervention lies beyond the theory. I theorize most rudimentary bimodal quantum experiments studied by Finkelstein [2], and deduce “bimodal probability density” π = |ψin>⊗<φfin| to represent complete quantum experiments. It resembles core insights of the Copenhagen theory.
